For several decades the debate over collective security--the idea that alliances are problematic and that all nations should pledge to come to the aid of any nation that is a victim of aggression--has been polarized. Collective Conflict Management and Changing World Politics probes the international and domestic conditions under which collective security tends to work or not, and questions if the end of the Cold War makes success more or less likely than before. The contributors conclude that collective conflict management is possible under specific situations, as they enumerate various domestic and international requisites that circumscribe such possibilities.
